Answer:
1 + net charge
Explanation:
The resulting ion will have
1 electron fewer surrounding the nucleus than the number of protons located inside the nucleus it will have a 1+ charge.
Answer:
Physical
Explanation:
Physical weathering is defined as the geological process in which rocks are broken down but there is no change in their chemical composition.
Granite tor are the rock masses above the ground surface which are associated with granites
Granite Tor is an example of physical weathering as they formed by freeze–thaw weathering. Granite tor are formed when magma present in the crust cools down and form batholith. Rocks above batholith gets erodes and left the batholith to expose.
Hence, the correct answer is "Physical weathering'.
Answer:
Pb(NO3)2 + 2NaCl = 2NaNO3 + PbCl2
Explanation:
The given data is as follows.
= 1.5 atm, = 20 L, = (28 + 273) K = 301 K
= 5 atm, = ?, = (50 + 273) K = 323 K
Formula to calculate the volume will be as follows.
=
Putting the given values into the above formula as follows.
=
=
= 0.64 L
Thus, we can conclude that the change in volume of the balloon will be 0.64 L.
The pressure of the gas is 3.52 atm
<u><em>calculation</em></u>
This is calculated using the Boyle's law formula
that is P1V1= P2V2 where;
P1 = 1.65 atm
V1 =22.8 L
P2 =? atm
V2 = 10.7 L
make P2 the subject of the formula by dividing both side by V2
P2 = P1V1 / V2
P2 = (1.65 atm x 22.8 l) / 10.7 L = 3.52 atm
